{"product_id":"sn74als243ans","title":"SN74ALS243ANS","description":"\u003cp\u003eThe SN74ALS243ANS is a quad bidirectional transceiver from Texas Instruments, part of the 74ALS logic family. It operates from a 4.5V to 5.5V supply, with output drive capability of 15mA (sink) and 24mA (source). The device features 3-state outputs and a single 4-bit channel, making it ideal for data bus applications. Housed in a compact 14-pin SOIC package, it is designed for 5V systems requiring bidirectional data flow with minimal power consumption. Common applications include microprocessor bus isolation and memory interfacing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBidirectional Data Flow: Simplifies read\/write operations on shared buses.\u003c\/li\u003e\n\u003cli\u003eHigh Source Current (24mA): Drives capacitive loads and long traces effectively.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Enables bus sharing with multiple devices.\u003c\/li\u003e\n\u003cli\u003eLow Power 74ALS Technology: Reduces heat generation in dense systems.\u003c\/li\u003e\n\u003cli\u003eCompact SOIC Package: Saves PCB space for portable designs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eMicroprocessor Bus Isolation\u003c\/h3\u003e\u003cp\u003eUse the SN74ALS243ANS to isolate the CPU data bus from peripherals.
